Description
- This application is a continuation-in-part of U.S. application Ser. No. 16/279,969 filed Feb. 19, 2019, which claims priority of Taiwan Patent Application No. 107111545, filed on Apr. 2, 2018. The entirety of each of said applications is incorporated herein by reference.
- This invention relates to a method and apparatus for generating power. More particularly, this invention utilizes atmospheric pressure and vacuum to repeatedly push water upwards through a pipeline to a vacuum chamber and let the water flow downwards to strike and rotate a hydraulic power generator to generate electricity.
- Power mostly comes from burning of petroleum, liquefied gas, coal, woods, etc. Because of carbon dioxide generated from all the burning, the resultant greenhouse effect, climate changes, and other adverse phenomena are increasingly threatening life on earth. As a result, it has become a universal goal for mankind to utilize clean or green energy, such as solar energy, wind power, hydroelectric power, geothermal energy, tidal energy, atmospheric pressure, etc.
- Solar energy is of very limited usefulness at nighttime and during cloudy days; wind power is unavailable or unreliable during windless days; reservoir hydroelectric power is unreliable during dry seasons; geothermal energy and tidal energy are certainly confined to particular geographical locations.
- In view of the above-mentioned disadvantages and limitations, the inventor undertook an in-depth analysis and research and, having endeavored for a long time and experimented repeatedly, completed the present invention.
- The purpose and objective of this invention is to generate electricity from atmospheric pressure, vacuum and gravity in a cost-efficient way. The invention utilizes atmospheric pressure to push water upwards through a pipeline to reach a vacuum chamber at a height of up to about 10.33 meters, then allows the water in the vacuum chamber to flow downwards by gravity to strike the turbine of a hydraulic power generator to generate electricity. The electricity generation cycle can repeat itself over and again using the apparatus according to the invention.
- The apparatus according to the present invention includes a main water tank containing water in communication with the atmosphere; an upward pipeline connecting the main water tank to a first vacuum chamber positioned at a desired height above the main water tank; a second vacuum chamber connected below the first vacuum chamber by a first downward pipeline; an intermediate water tank adjoined to a lower portion of the second vacuum chamber; a second downward pipeline connected to the bottom side of the intermediate water tank; a return pipeline connected between the second downward pipeline and the upward pipeline; and an upward-extending air pressure cylinder connected to a middle side port of the return pipeline.
- Furthermore, a power generating assembly including a water wheel, a speed increaser gearbox and a generator is installed inside the second vacuum chamber. The return pipeline is connected to a lower side port of the upward pipeline through a first normally closed (NC) solenoid valve and connected to a lower end of the second downward pipeline through a second NC solenoid valve. The return pipeline has a pair of two adjacent normally open (NO) solenoid valves equipped in a middle portion thereof. The air pressure cylinder has a piston disposed inside and connected to an extension spring and an upper space connected to the atmosphere through a third NC solenoid valve. A water supply valve is disposed at a lower end of the upward pipeline for allowing or stopping water flow from the main water tank.
- By properly opening or closing the valves of the apparatus, a continuous closed space including the first vacuum chamber, the second vacuum chamber and the air pressure cylinder may be formed within the apparatus. Then, after a vacuum is created in the continuous closed space, and the water supply valve of the upward pipeline is turned open, the water in the main water tank will flow through the upward pipeline to the first vacuum chamber, then downward to the second vacuum chamber through a nozzle of the first downward pipeline, such that the water will strike the water wheel of the power generating assembly inside the second vacuum chamber to generate electricity. Afterwards, the water will be directed by time-controlled opening and closing operations of the NC solenoid valves and the NO solenoid valves to again flow through the upward pipeline to the first vacuum chamber and the second vacuum chamber in repetitive cycles of power generation.
- By adding one or more height elevating assemblies between the upward pipeline and the first vacuum chamber in the apparatus, the first vacuum tank can be raised to essentially any desired altitude, thereby increasing the impact force of the down-flowing water on the water wheel for higher power generation.
- Such apparatus can run 24 hours a day, 7 days a week. It can be installed in the backyard of a house or in a factory, regardless of whether it is in a frigid zone, temperate zone, or torrid zone. It generates electricity at low cost without any use of fossil fuel.

- A first embodiment of the apparatus and method for generating electricity using atmospheric pressure and vacuum (and gravity) according to the present invention is illustrated in
FIG. 1 . The apparatus includes: amain water tank 2 containing water in communication with the atmosphere via anopening 3; afirst vacuum chamber 1 positioned at a height (of up to 10.33 meter) above the level of water in themain water tank 2; anupward pipeline 5 connecting themain water tank 2 to thefirst vacuum chamber 1; asecond vacuum chamber 11 positioned below thefirst vacuum chamber 1 and above themain water tank 2; a firstdownward pipeline 6 connecting thefirst vacuum chamber 1 to thesecond vacuum chamber 11; apower generating assembly 7 disposed inside thesecond vacuum chamber 11; anintermediate water tank 20 adjoined to a lower portion of thesecond vacuum chamber 11 and in fluid communication with thesecond vacuum chamber 11; a seconddownward pipeline 21 with an upper end connected to the bottom side of theintermediate water tank 20; areturn pipeline 26 connected between a lower end of the seconddownward pipeline 21 and alower side port 27 of theupward pipeline 5; and anair pressure cylinder 22 with apiston 25 therein and vertically connected from above to amiddle side port 24 of thereturn pipeline 26. - Furthermore, as shown in
FIG. 1 , theupward pipeline 5 is equipped with a water supply valve (e.g. a manual stopcock valve) 4 for blocking or admitting the water flow from themain water tank 2 into theupward pipeline 5. Thewater supply valve 4 is positioned lower than thelower side port 27 of theupward pipeline 5. The lower end of the firstdownward pipeline 6 is formed as or fitted with anozzle 13 for forming a jet stream from the water following through the firstdownward pipeline 6. - The
return pipeline 26 is connected to thelower side port 27 of theupward pipeline 5 through a first normally closed (NC)solenoid valve 17 and is connected to the lower end of the seconddownward pipeline 21 through a secondNC solenoid valve 18. It is noted that each of the twoNC solenoid valves downward pipeline 21, thereturn pipeline 26 is substantially horizontal at the level of thelower side port 27 of theupward pipeline 5. Therefore, thesecond vacuum chamber 11 and the adjoiningintermediate water tank 20 are both at a level above thereturn pipeline 26. Thereturn pipeline 26 is further equipped with a pair of two adjacent normally open (NO)solenoid valves 16A,16B between themiddle side port 24 and the secondNC solenoid valve 18 at a location near themiddle side port 24. Specifically, the firstNO solenoid valve 16A is positioned closer to themiddle side port 24 than the second NO solenoid valve 16B. It is noted that each of the twoNO solenoid valves 16A,16B is closed when energized (by electricity supplied thereto), but open when de-energized. In this embodiment of the present invention, the twoNO solenoid valves 16A,16B are open or closed at the same time. Therefore, each one may be considered as a backup for the other; or the two may be treated as oneNO solenoid valve 16, as in the following description. - Moreover, in this embodiment, whenever the NO solenoid valve 16 (16A/16B) is open, the first
NC solenoid valve 17 is closed, and vice versa, so the operations (i.e. opening or closing) of the firstNC solenoid valve 17 and the NO solenoid valve 16 (16A/16B) may be controlled as a group by one timer-controller (not shown), whereas the operations of the secondNC solenoid valve 18 may be controlled by another timer-controller (not shown). - The
second vacuum chamber 11 is equipped with a vacuum valve 9 (through which air may be drawn out to create vacuum), avacuum pressure gauge 8, and aliquid level probe 10 extending through thesecond vacuum chamber 11 and into theintermediate water tank 20. Thepower generating assembly 7 includes a water wheel (or turbine) 12 located in a position corresponding to thenozzle 13 of the firstdownward pipeline 6, a speed increasergearbox 14 connected to the water wheel (or turbine) 12, and agenerator 15 connected to the speed increasergearbox 14. When thewater wheel 12 is struck and turned by the water stream flowing down through thenozzle 13, it rotates the speed increasergearbox 14 and thegenerator 15 to generate electricity. Generally, thegenerator 15 includes a stator and a rotor (not shown). Since the components and operational principle of thepower generating assembly 7 are well known in the art, they will not be further described. Suffice to say that a sufficient height differential should be maintained between thefirst vacuum chamber 1 and thesecond vacuum chamber 11. - For proper operations of the apparatus of the present invention, the
intermediate water tank 20 has a storage capacity larger than that of thefirst vacuum chamber 1. The purpose of theliquid level probe 10 is to keep the water level in theintermediate water tank 20 from getting too high by sending a warning signal or alarm when the water level in theintermediate water tank 20 reaches the lower end of theliquid level probe 10. Suffice to say that the water level in theintermediate water tank 20 is regulated or controlled by a liquid level controller (not shown) in conjunction with theliquid level probe 10. - As further illustrated in
FIG. 1 , thepiston 25 inside theair pressure cylinder 22 is connected to the lower end of anextension spring 19, which is fixed at its upper end to the top inner wall of theair pressure cylinder 22. The internal space of theair pressure cylinder 22 is divided into two by the piston 25: the upper space (on the same side as the extension spring 19) is in air communication with the atmosphere via a third normally closed (NC) solenoid valve 28 (when it is energized to open so as to act as an air hole), and the lower space (under the piston 25) is in fluid communication, through themiddle side port 24 of thereturn pipeline 26, with thereturn pipeline 26, the seconddownward pipeline 21 and the intermediate water tank 20 (when theNO solenoid valve 16 and the secondNC solenoid valve 18 are open). The operations of the thirdNC solenoid valve 28 may be controlled by yet another timer-controller (not shown). - As also shown in
FIG. 1 , thegenerator 15 is connected by a cable to themain power switch 30, which is connected tosub-power switches generator 15 is transmitted to themain power switch 30 and then distributed to each of the sub-power switches 31, 32 and 33. In this embodiment, the sub-power switches 31 and 33 are used to supply electricity to the power grid or directly to end users; thesub-power switch 32 is connected to the liquid level controller for monitoring/controlling the operations of theliquid level probe 10 and the timer-controllers mentioned above for controlling the operations of the NO solenoid valve 16 (16A/16B) and theNC solenoid valves sub-power switch 32. Therefore, the overall timer-controller will be considered in the following description of the present invention. Since the components and operational principle of the timer-controller for controlling the operations of NC or NO solenoid valves are generally known in the art, they will not be further described. - With the above-described apparatus, the method according to the present invention for generating electricity using atmospheric pressure and vacuum proceeds as follows:
- (A) close the
water supply valve 4 of theupward pipeline 5 and open the second NC solenoid valve 18 (using an external power source) while keeping the NO solenoid valve 16 (16A/16B) open so that a continuous closed space is formed in the apparatus, including theupward pipeline 5, thefirst vacuum chamber 1, the firstdownward pipeline 6, thesecond vacuum chamber 11, theintermediate water tank 20, the seconddownward pipeline 21, thereturn pipeline 26, and the space under thepiston 25 in the air pressure cylinder 22 (with the thirdNC solenoid valve 28 closed); - (B) connect a vacuum pump (not shown) to the vacuum valve 9 of the
second vacuum chamber 11 and operate the vacuum pump to create a vacuum in thesecond vacuum chamber 11 and throughout the continuous closed space in the apparatus; - (C) close the vacuum valve 9, then open the
water supply valve 4 of theupward pipeline 5, upon which water in themain water tank 2, under atmospheric pressure through theopening 3 of themain water tank 2, flows into and fills up the continuous closed space while pushing thepiston 25 in theair pressure cylinder 22 upwards, until the water in theintermediate water tank 20 reaches a preset level; in the meantime, water flowing down from the firstdownward pipeline 6 strikes and turns thewater wheel 12 for thegenerator 15 to start generating electricity; - (D) close the
water supply valve 4, and set the apparatus to the auto mode: namely, set the power source for the liquid level controller (with the liquid level probe 10) and the overall timer-controller to thesub-power switch 32, which draws power from thegenerator 15; - (E) upon entering the auto mode, the apparatus proceeds with the power generation cycle in the following sequence:
-
- (1) Open the first
NC solenoid valve 17; close theNO solenoid valve 16 and return the secondNC solenoid valve 18 to its closed status; and open the thirdNC solenoid valve 28. At that instant, air follows through the thirdNC solenoid valve 28 into theair pressure cylinder 22, pushing down thepiston 25 and extending the extension spring 19 (as shown inFIG. 3 ), driving the water under thepiston 25 of theair pressure cylinder 22 to flow out through themiddle side port 24 of thereturn pipeline 26, the firstNC solenoid valve 17, theupward pipeline 5, thefirst vacuum chamber 1, the firstdownward pipeline 6, and thenozzle 13, striking and turning thewater wheel 12 and therefore thegenerator 15 to generate electricity, as described earlier.FIG. 3 illustrates thepiston 25 having been pushed down and theextension spring 19 extended in theair pressure cylinder 22 to drive water out of theair pressure cylinder 22. - (2) After a preset time period T1 (normally about a second), return the third
NC solenoid valve 28 to its closed status. Because theextension spring 19 is no longer under the atmospheric pressure through the third NC solenoid valve 28 (in the closed status), theextension spring 19 quickly returns to its unextended state, while starting to carry water up through themiddle side port 24 of thereturn pipeline 26 to enter the space under thepiston 25 in theair pressure cylinder 22. - (3) After a short preset time period T2, open the second
NC solenoid valve 18 and theNO solenoid valve 16, and return the firstNC solenoid valve 17 to its closed status. At that instant, water flows from theintermediate water tank 20 through the seconddownward pipeline 21 and the secondNC solenoid valve 18 into thereturn pipeline 26 and then through theNO solenoid valve 16 and themiddle side port 24 to completely fill up the space under thepiston 25 in theair pressure cylinder 22 after theextension spring 19 returns to its unextended state.
- (1) Open the first
- (4) Wait for a preset time period T3 to allow step (3) to run its course.
- The auto mode described in step (E) will repeat itself over and again.
- According to the foregoing description, the method and apparatus according to the present invention can generate electricity in repetitive cycles, 24 hours a day, 7 days a week. The apparatus can be installed in the backyard of a house or in a factory, regardless of the local climatic or weather conditions.
- When a relatively larger capacity of power generation is demanded, a larger flow rate or a larger impact force is required of the water stream from the
nozzle 13 to strike and rotate thewater wheel 12. To accomplish this, the height of thefirst vacuum chamber 1 over thewater wheel 12 need be increased to increase the pressure differential, and theupward pipeline 5 and the diameters of the firstdownward pipeline 6 need be lengthened. Moreover, the various pipelines in the apparatus may have to be larger in diameter. -
FIG. 2 illustrates a second embodiment of the present invention for this purpose. As shown inFIG. 2 , instead of connecting theupward pipeline 5 directly to thefirst vacuum chamber 1, theupward pipeline 5 is connected to aheight elevating assembly 40, which is in turn connected to thefirst vacuum chamber 1. - The
height elevating assembly 40 includes anaccessory vacuum chamber 1′, which is connected to theupward pipeline 5 of the apparatus shown inFIG. 1 and to adownward pipeline 21′, a secondNC solenoid valve 18′, areturn pipeline 26′, aNO solenoid valve 16′ (or a pair of adjacentNO solenoid valves 16A′,16B′), anair pressure cylinder 22′ equipped with a thirdNC solenoid valve 28′, a firstNC solenoid valve 17′, and anupward pipeline 5′ (without a water supply valve), which is connected to thefirst vacuum chamber 1 of the apparatus shown inFIG. 1 . Essentially, theaccessory vacuum chamber 1′, thedownward pipeline 21′, the secondNC solenoid valve 18′, thereturn pipeline 26′, theNO solenoid valve 16′ (16A′/16B′), theair pressure cylinder 22′, the firstNC solenoid valve 17′ and theupward pipeline 5′ in the second embodiment are respectively the same in structure and function as thefirst vacuum chamber 1, the seconddownward pipeline 21, the secondNC solenoid valve 18, thereturn pipeline 26, theNO solenoid valve 16′, theair pressure cylinder 22, the firstNC solenoid valve 17 and theupward pipeline 5 of the apparatus of the first embodiment described earlier, except that the upper end of thedownward pipeline 21′ is connected to theaccessory vacuum chamber 1′. - As shown in
FIG. 2 , thefirst vacuum chamber 1 in this embodiment is elevated to an altitude higher than is thefirst vacuum chamber 1 in the embodiment shown inFIG. 1 . Theupward pipeline 5 and thedownward pipeline 6 in this embodiment are extended and elevated higher than their counterparts inFIG. 1 . Therefore, the water flowing from thefirst vacuum chamber 1 through thesecond pipeline 6 will strike thewater wheel 12 with a larger impact force and generating more electricity. -
FIG. 2 shows just oneheight elevating assembly 40, however, more than one height elevating assembly may be provided between theupward pipeline 5 and thefirst vacuum chamber 1 to increase the height of thefirst vacuum chamber 1 over thewater wheel 12. - From the foregoing, the method and apparatus for generating electricity according to the present invention has the following advantages:
- 1. it is not limited by the geographical or climate conditions and is environmentally friendly; the apparatus may be installed in almost all locations for around-the-clock operations.
2. it is easily scalable by adding intermediate height elevating assemblies and/or increasing the diameter of the pipelines to increase the flow rate and impact force of the water to produce more electricity;
3. it consumes little electricity to start its operation and can continue to generate electricity perpetually afterwards. - In the apparatus of the present application, water is used due to its great abundance and wide availability on earth. However, other liquids can certainly be used instead of water. In the embodiments discussed above, the vacuum valve 9 and the
vacuum pressure gauge 8 are installed on thesecond vacuum chamber 11 for creating a vacuum in the apparatus. Nevertheless, the vacuum valve 9 and thevacuum pressure gauge 8 may be disposed on thefirst vacuum chamber 1 instead of, or in addition to, thesecond vacuum chamber 11. - Because a prior art search did not find any identical or similar structure existing prior to this application. this invention meets patentability requirements and should be patentable.
- The foregoing are merely some preferred embodiments of this invention and should not limit the claims of the present application as a result. Changes of equivalent structures which apply this invention's instructions and claims are all included in the claims of this invention for the same reason.
